Description

A 360-degree rotatable LED dimming downlight

technical field

The utility model relates to the field of lighting fixtures, in particular to a 360-degree rotatable LED dimming downlight.

Background technique

Downlights have the advantages of soft light, bright, exquisite appearance, luxury, etc., and are widely used in interior decoration of homes, shops, businesses, and high-end hotels. At present, the downlight light source is mainly a traditional light source, because the traditional light source is a thermal light source, its luminous efficiency is low, its life is short, and its power consumption is relatively large. With the development of science and technology, the luminous efficiency and color rendering index of LED light sources are gradually improving, becoming the best choice to replace traditional light sources. The lighting market in the 21st century will be dominated by LED lighting.

Due to the long service life of LED, low energy consumption and significant energy saving, LED light sources have been widely used in daily life, such as lamp cups, spotlights, downlights, bulbs, wall washers, street lights, car lights and other LED lighting lamps. However, with the increase in the number of LEDs in LED lamps and the development of high-power and high-brightness LEDs, the heat generated by LED lamps is gradually increasing. Therefore, how to quickly dissipate the heat generated by LED lamps has become a major problem that must be solved in current LED lamp technology.

Existing LED downlights mainly consist of an aluminum alloy shell, an aluminum substrate, and LEDs mounted and fixed on the aluminum substrate. The aluminum substrate is installed in the casing and connected to the casing. The thermal conductivity of the shell itself can conduct away the heat generated by the LED when it is working. However, due to the small volume of the aluminum substrate, the heat dissipation efficiency is not high. However, the LED lamp shell is limited by the appearance shape, and its heat dissipation effect is poor, and it cannot promptly and quickly conduct away a large amount of heat generated by the LED when it is working, resulting in a shortened service life of the LED.

Most of the existing LED downlights are non-dimmable products. LED downlights work at full load for a long time and often work at high temperatures, which affects the life of LED lamps and fails to achieve the best energy-saving purpose.

Contents of the invention

The purpose of this utility model is to improve the heat dissipation effect of the LED downlight, the multi-directional activity mode and the brightness of the LED light, so that the LED downlight has a beautiful appearance, a longer life, and a more energy-saving 360-degree Turnable LED dimming downlight.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a 360-degree rotatable LED dimming downlight, including LED light source, light source bracket, radiator body, decorative components, installation circlip, LED driver; its features In that: the heat sink body is evenly distributed with a plurality of heat dissipation ribs; the LED light source is arranged on the upper part of the heat sink body, directly contacts with the heat sink body, and is fixed by the light source bracket; it also includes a spotlight reflector and The light-transmitting part, the condensing reflective cup is fixedly installed on the light source bracket, and the LED light source is located at the center of the bottom of the condensing reflective cup; the light-transmitting part is installed on the upper part of the condensing reflective cup; the decorative component is installed On the upper part of the radiator body, the installation clip is fixed on the outside of the decoration component.

Further, the decorative component includes a decorative circular pressure ring, a decorative spherical inner ring and a decorative circular panel, the decorative circular pressure ring is set on the light-transmitting member, and the decorative spherical inner ring is sleeved on the light-concentrating reflective The outer side of the cup is riveted and fixed with the decorative circular inner ring. The decorative circular panel is sleeved on the outer side of the decorative spherical inner ring and connected to the radiator body through an aluminum connector, and the decorative circular panel and the decorative circular inner ring are connected by a spherical surface. Cooperate to realize installation and rotation.

Preferably, the LED driver is a dimming driver.

By adopting the above technical scheme, the 360-degree turnable LED dimming downlight described in the utility model greatly increases the heat dissipation area by setting the heat dissipation ribs, so that the heat generated by the LED is directly transmitted to the radiator body, and has a good heat dissipation effect. At the same time, the LED dimming driver is used to adjust the brightness so that the LED light source does not always work at full power, so that the LED light source can achieve a longer service life and be more energy-saving; in addition, the decorative circular panel and the decorative circular inner ring are spherical With the installation and rotation, the purpose of 360-degree rotation of the downlight can be realized.
